depends of its still air or windy. I know id check the wind direction sometimes. I can smell people blazing up driving behind them sometimes in the car.... Tip is to blaze that shit away from neighbors so that the smoke rises enough and by the time the "cloud" gets in their area its diffused enough or UP in the air. Sort of similarly to smoking outside a closed door..if you go back in right after smoking the smell could follow you in..Hang tight for a sec.
